Cutting across a cloud point

I have a guess a very simple question, unfortunately I can’t figure it out.
Recently we started working with 3D scanners and we have .xyz files that I can open in Rhino and have a look around.
My question is how can I create a similar thing like the bounding box in ReCap, so that I can get rid of the roof for example?

Hi -

It sounds like you should be able to achieve what you want by using a ClippingPlane.

Ahh, yes I didn’t check if ClippingPlane will work. It does. Thank you for the quick reply.
